/* ** ** Swift/XRT hardness ratio for Mrk 421. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 59285.328514 0.000749 0.15593 0.01241 0.97297 0 24.80795 0.71968 9.84866 0.28548 3.86839 0.28662 1.53936 0.11404 59285.330033 0.000770 0.15680 0.01230 0.96992 0 25.21106 0.72009 9.65624 0.27583 3.95302 0.28885 1.51277 0.11055 59285.331483 0.000680 0.18019 0.01400 0.98298 0 24.63777 0.74981 9.56732 0.29113 4.43948 0.31726 1.72520 0.12328 59285.332889 0.000726 0.16263 0.01273 0.98406 0 25.12775 0.73123 9.80452 0.28521 4.08646 0.29691 1.59245 0.11568 59285.334356 0.000741 0.16432 0.01270 0.97656 0 25.11622 0.73024 9.65420 0.28068 4.12713 0.29567 1.58607 0.11363 59285.335907 0.000810 0.15817 0.01235 0.96786 0 24.01650 0.68535 9.18945 0.26218 3.79865 0.27601 1.45142 0.10543 59285.338141 0.001424 0.16210 0.00922 0.97764 0 24.77253 0.52365 9.50902 0.20095 4.01561 0.21214 1.54401 0.08154
